>A uudecode utility must have the following attributes to be usable with

|
|
|
|
Sounds like I already got most of them last night! I'll mail you an alpha
|
|
version later today for your preliminary evaluation.
|
|
|
|
>No splash screen or registration dialog or other display that the user must
|
|
>dismiss, at least not when launched with an ODOC event.
|
|
|
|
Check.
|
|
|
|
>No standard file prompt for destination file name and location. Use the
|
|
>file name from the uuencode header line, and put the decoded result file in
|
|
>the same folder as the input file.
|
|
|
|
Check.
|
|
|
|
>Append digits or something if necessary to guarantee unique destination
|
|
>file name.
|
|
|
|
Check.
|
|
|
|
>Launchable in background. Do not assume you start out in the foreground.
|
|
|
|
Check.
|
|
|
|
>Use Notification Manager properly if you are in the background before
|
|
>presenting error alerts or other dialogs.
|
|
|
|
Check -- right now there *are* no error alerts or dialogs. (This may change, of
|
|
course :-)
|
|
|
|
>Must be drag-and-drop, of course: Drop a text file on the utility, and it
|
|

|
|
|
|
Check.
|
|
|
|
>Must be able to accept additional ODOC events while busy, and queue them.
|
|
>In NewsWatcher, if the helper app is already running, I just send it an
|

|
|
|
|
I think this works, but will check it. All WaitNextEvent() calls during the
|
|
processing have an event filter of (everyEvent - highLevelEventMask), so things
|
|
should queue up in the OSEvent queue until I get back to the main event loop.
|
|
|
|
>Must delete input file after successful decode, or at least offer this as a

|
|
|
|
Not done yet, but planned as an option.
|
|
|
|
>Must be able to handle multiple-part uuencoded text with intermixed headers
|

|
|
|
|
Check. (This was one of the really cool features of my unix version :-)

|
|
|
|
|
>The following attributes are highly desirable:

|
|
|
|
Check.
|
|
|
|
>Should have configurable preferences for file name suffix -> file type and
|
|

|
|
>default for gif and jpeg files in Expander, by the way. With Expander, you
|
|

|
|
|
|
Not yet, but planned. At first, I'll probably just do something similar to the
|
|
Stuffit Engine until I have time for going all out.
|
|
|
|
>Should run like a bat out of Hell in native mode, of course. :-)
|
|
|
|
Check -- faster than Leonard's, even :-)
|
|
|
|
>Should call WaitNextEvent every 4-6 ticks while busy, no more and no less,
|
|
>to cooperate well with other apps.
|
|
|
|
I'm using a sleep time of 3 ticks while busy, and making sure I don't call
|
|
WaitNextEvent any more often than every 2 ticks. It *still* runs like a bat out
|
|
of hell, though.
|
|
|
|
>Should *not* slow down when run in the background.
|
|
|
|
Check.
|
|
|
|

|
|

Check.
|
|
|
|

|
|

|
|
|
|
Hadn't thought of that, but it's a good idea. I'll put it in.
|
|
|
|
Thanks for the checklist -- it makes my job a lot easier. Maybe you can even
|
|
distribute my app with NewsWatcher if you like it enough. I don't really care
|
|
what you do with it; I'm writing it for my own reasons, anyway :-)
